The US Agency for International Development (USAID) on February 19
announced that it has contracted with TerraTherm Inc. to carry out
thermal remediation of dioxin at Da Nang airport in the central city
of the same name.
TerraTherm’s remediation
technology plays a vital role in the US-funded project’s efforts to
clean up dioxin contamination from Agent Orange the airport where it was
stored and handled during the war, according to USAID’s press release.
The agency is working in close coordination with the
Vietnamese Government and other contractors to implement this ongoing
project through 2016.
USAID selected TerraTherm’s
In-Pile Thermal Desorption (IPTD) technology for treatment of
approximately 73,000 cubic meters of soil and sediment at Da Nang
Airport .
The IPTD approach incorporates placing
contaminated soil and sediment within an above-ground, covered and fully
insulated treatment pile structure, and then heating each batch of soil
over several months to destroy the dioxin.
Once
implemented, the technology can safely and effectively treat the soil to
the required Vietnamese cleanup levels, as has been demonstrated at
similarly-sized projects in the US .
TerraTherm is working with Krüger/VWS-VN to implement the project.-VNA
